FEEDING "DEVICE.

Application filed November 26, 1923. Serial No. 677,021.

To all whom it may concern."

Be it known that 1, Joan MANOFSKY, a citizen of the United States, residing at Warren, in the county of Trumbull and 5 State of Ohio, have invented a new and useful Improvement in Feeding Devices, of which the following is a specification.

The present invention relates to improvements in feeding devices more particularly 1 in such devices intended for feeding sheet metal blanks to devices for operating thereupon, such as slitters, cutters and the like. The invention will be fully understood from the following description, illustrated by the 15 accompanying drawings, in which a device embodying the invention is shown.

Referring more particularly to the drawthe line i l elevation of the device of ings, the numerals 11, 11 designate parts 0' the device for operating for example, a pair of slitting cutters. They are mounted in a cutter frame 12, which may be suitably constructed for example, as shown in the co-pending application of W. W. Galbreath, Serial No. 613,674, filed January 9, 1923. The blank is fed to the cutters 11 along a feed table 13, and passes through a suitable guide 1 just prior to enterin the cutters 11. The feed table 13 may suitably be provided with side rails 15, for guiding the blanks fed therealong.

At a suitable point near the cutters ii, well or depression 16 is formed inthe bed of the feed table 18, and in this is journaled a feed roll 17 which may be driven by any suitable means, for example, the flexible shaft 18. This "feed roll 17 is so positioned in the well that its upper surface may ongage and act upon the lower surface of blank fed along the-surface ofthe table lB, such a blank being designated by the nu meral 1.9 on the drawings.

Above the feed roll 1! and co-operating therewith is a feed roll 20, which is joui naled in the side members 21 of a yoke 21 pivotally mounted on a shaft 22 mounted on standards23 secured to the sides of the feed table 13. The two side members 21 of the yoke join together to form a projecting member 24: in which is journaled a roller 25, the function and operation of which will be more fully hereinafter described. It will be apparent from the structure already de scribed that upward movement of the yoke members 21 will raise the feed roll 20 out of cooperative relationship with Above the roll 2'? is provided a cooperating the roll 1? and the blank fed between the rolls.

tlll

roll 29, the ends of which are journaled in arms 30 pivoted on shafts 31. Rolls 27 and .29 are provided with intermeshing gears 32.

By reason of the mounting of the upper roll 29 upon the pivotally mounted arms 30, the roll 29 may be moved vertically with respect f to the roll 27. upon metal blanks,

it will be apparent from the foregoing that a blank. as it moves alon the feed table, is acted upon by rolls 17 an 20, which feed it along until it encounters the rolls 27 and 29. The rolls 2'? and 29 are so constructed that the movement of the blank therebetween raises the upper roll 29 and holds it in. raised position until the entire blank has passed therebetween. As hereinafter pointed out, the rolls 2? and 29 are also caused to elevate the upper feed rolls 20-, thereby preventing further co operation ltlli llld of this roll with the feed roll 17 in feeding the blanks forwardly, and the roll 29 is also caused to provide a check or stop to forward movement of a second blank during passage of the first blank through the machine.

As shown best in Fig. 8, the surface of i the portions of .the roll 29 co-operating with vided with eccentric bulges 29 oncoming blank, are provided with eccentrieally' depressed portions 29*, terminating in shoulders 29. The inserts 29, are pro -The insert 29" has its surface serrated or knurled, and

' i the entire surface of the roll 29 may also be on the roll 29. The insert 27 rated or knurled, and the surface 27 may the roll.

knurled if desired. The roll 27 has the greater portion of its surface cylindrical, as at 27 and is provided with hardened metal inserts 27, the contour of which follow the cylindrical contour of the surface 27*. A depression 27 site the position of th eccentric bulge 29 may be serlikewise be knurled or otherwise roughened,

.if desired.

' The roll 29 is provided, for example, near one end, with a cam shoulder 35, this cam portion being suitably portion 34 having a cut into the body of the roll; A projecting stop member 36 is secured to a support 37 mounted upon the supporting frame 26, and is so positioned as to be slightly above the path of the shoulder 35 when rolls 27 and 29 engage each other. When, however, the roll 29 is raised by the passage of a blank between it and the roll 27, as hereinafter described, the cam portion 34L is also raised and the shoulder 35 engages the stop 36 in its movement, and the rotation of the roll '29 is thereby stopped. The roll 29 is provided with a second cam portion 38, formed with a raised portion ing suitabl' cut into the central ortion of mally engages this cam.

In operation, a blank 19 is fed along the table 13, and is engaged by the feed-rolls 17 and 20 which cause its forward movement toward the cutters 11. As the blank 19 approaches the cutters, it passes into ,the bite of the rolls 27 and 29, which are in the position shown in Fig. 8. The forward movement of the blank causes the rotation of these rolls, which move together by reason of the intermeshing of the gears 32. As the portion of the roll 29 first engaged (29) .is eccentrically depressed, the rotation of the roll 29 causes it to berais'ed, this rising is formed in the roll 27 oppo-.

39, the cam be he roller25 of the yo e21 nor movement being permitted by the mounting of the roll on the pivoted arms 30. The

gears 32 remains inmesh, and the roll 29 continues to rotate. .The rise of the roll 29 brings the cam 34 into such position that the The rolls 27 and 29 are then in the position relative to the blank traveling be- 7 tween them shown in Fig. 8, and are held stationary by the impin ement of the shoulder 35 on the stop 36. y this time the sheet has reached the cutters 11, which cause its further forward movement. The rolls 27 and 29 remain stationary, the sheet slid,- ing between th insert 27 of the roll 27 and the insert 29 of the roll 29. By the movement of the roll 29, thecam 38 has been brought into such position that the yoke 24 is raised, and with it the roll 20. Theroll 20 thus becomes inoperative. If a second sheet is fed along the table on top of the blank 19 before the latter tirely to the cutters, the roll 20 is no longer effective to force it forward toward the roll. As the end of such a blank moves forward on top of the blank 19,- it engages the shoulder 29 on the roll 29, which isheld has passed en stationary as long as the blank 19 is passing P feed roll 20 is also lowered, the feed rolls 17 and 20 again co-operate and the incoming blank is forced ahead, the operations being repeated with the new blank.

Although the present invention has been described in connection with the specific details of a construction embodying it, it is not intended that theseshall be regarded as limitations upon the scope of the invention,

except in so far as included the accompanying claims.
